Effects of acid rain on plants

However, sheltered areas on limestone and marble buildings and monuments show blackened crusts that have spalled peeled off in some places, revealing crumbling stone beneath. But recovery takes time, and soils in the northeastern U. Sandstone is also primarily composed of silica and is thus resistant. This is especially true of trees at high elevations in various regions of the U. The major biological source of sulfur compounds is dimethyl sulfide. The normal pH of rain is around 5. Nitrogen oxides are formed through the extreme heating of air when a thunderstorm produces lightning. Acid rain leaches aluminum from the soil. That combination makes waters toxic to crayfish, clams, fish, and other aquatic animals. Bibliography American Chemical Society. A few sandstones are less resistant because they contain a carbonate cement that dissolves readily in weak acid.

The use of tall smokestacks to reduce local pollution has contributed to the spread of acid rain by releasing gases into regional atmospheric circulation. Solutions There are several solutions to stopping manmade acid rain.
